Is it possible to divert the flue laterally? Can the kitchen gas pipes be changed at will?

Under normal circumstances, commercial housing cannot be changed (except for villas and self-built houses). Because the main purpose of the flue is to prevent fumes from escaping into the kitchen of the upstairs neighbor's house, it is not a straight pipe. Each floor is equipped with a partition, if the owner changes the direction of the flue opening without permission, the partition floor will not have the effect of exhausting smoke, resulting in fumes running around.

If it is an independent household such as a villa or a self-built house, it can be renovated independently according to the site. However, commercial housing in general, especially high-rise residential buildings.

This flue is shared, and the position of this flue cannot be changed.

When the flue mouth was built in the house, the developer had already set it aside, mainly to remove the oil fumes generated by cooking in the kitchen. Some owners are not satisfied with the preset flue opening position, so they want to change it themselves, but can the kitchen flue change the position? What problems should be paid attention to when installing the flue mouth?

Let's learn now.

1. Can the kitchen flue be relocated?

Commercial housing cannot be changed (except for villas and self-built houses). Because the main purpose of the flue is to prevent the smoke from escaping to the kitchen of the neighbor upstairs, it is not a straight pipe, each floor is equipped with a partition, if the owner changes the direction of the flue opening without permission, the partition will not have the effect of exhausting the smoke, resulting in the smoke channeling, resulting in the flue of their own house and the neighbor's house is not smooth.

2. What are the precautions for the installation of kitchen flue?

1. The auxiliary flue must be retained.

The flue is divided into the main flue and the auxiliary flue, in which the main flue is responsible for the whole building, while the auxiliary flue is relatively independent, and the kitchen fume enters the main flue through the auxiliary flue first. If the auxiliary flue is directly connected to the main flue, it is very likely that the pressure is too low, and the phenomenon of smoke pouring and stringing smoke will occur.

2. Pay attention to the construction details.

The location of the hood is very important, and of course the shorter the pipe, the better the smoke exhaust effect. Some users will be beautiful, the flue is stretched longer, and after the range hood is closed, the oil smoke stored in the pipe cannot be discharged, and then poured back into the kitchen.

3. Pay attention to safety in window smoke exhaust.

In order to reduce the problem of smoke stringing in the flue, some users re-open the hole in the window instead of using the original flue, which is not allowed. Because the material at the end of the smoke exhaust pipe is metal, if the opening hole is relatively small, when the metal pipe transfers heat, it will cause the danger of glass bursting, and even hurt passers-by, and if the smoke pipe leads to the window, when the north wind blows indoors, there may be a situation of oil smoke backfilling.

Your question is to ask if it is okay to divert the flue laterally? This situation is definitely not possible, that is to say, the flue is generally upward, if it is a flat action, then there must be a forced circulation, so that it can be.

If it is said that the flue in the home needs to be changed, try not to change it to horizontal, because the horizontal is not particularly ideal for the direction of the flue in the home.

It can't be changed at will, but it can only be changed reasonably according to the actual situation.

It is true that there will be a problem of back-and-forth smoking, which is a highly carcinogenic, so every family should be on guard. How can this hidden danger be eliminated? Only by modifying the flue can the purpose of not stringing smoke be achieved.

I think there are two ways. The first is horizontal transformation. Theoretically, it can be discharged from the main flue, but in fact, part of the fume will enter the auxiliary flue on the 7th and 9th floors from the main flue and then be discharged into the 7th and 9th floors through the range hood.

A kind of straight discharge type, exhaust gas straight out, another kind of external discharge and ask the lower part to be equipped with a ninety degree right-angle cylinder, exhaust gas just turn to the bottom straight row, originally this structure is provided for the user on the first floor, so as not to exhaust to the passer-by, but if the upstairs user is installed with this kind of turning exhaust fan to put the stove under the window. The smoke machine is out of the air and walks out of the window. Everything was worked out.

I can't walk through the window. You can punch holes in the wall and walk through the wall. But you just need to block the mouth of your own common flue.

Because each user has a flue gas one-way check valve. The cause of the flue gas evacuation problem may be the blockage of the common flue, or the failure of your one-way check valve, or the failure of the topmost flue gas extraction equipment. Unplug the air duct of the range hood, use a chopstick to push the damper flap to see if it is opened and closed smoothly, and clean or replace it if it is stuck.

If there is no check damper, you need to install one, which is not expensive, and you can install it yourself.

The ground floor is inflated by a make-up air outlet. The principle is that each layer of flue gas is driven by the range hood to discharge the fume into the flue, and due to the effect of the flue gas temperature, the rising buoyancy is generated in the flue, and the flue gas is discharged from the air outlet of the roof. Generally, the flue is divided into the main flue and the auxiliary flue, the auxiliary flue is used to connect the exhaust holes of each range hood, and the auxiliary flue of the whole building is gathered into the main flue.

The main flue is unobstructed as a whole, and it is responsible for the emission of oil fumes in the whole building. When installing the range hood, be sure to punch holes in the auxiliary flue.

If there is only one street, it is convenient to improve it, so it is easier and easier to change it to two streets.

Add a smoke exhaust pipe so that the smoke exhaust pipe can be combined with the common flue.

You can open another lower flue, so that it will be very convenient to exhaust smoke up and down at the same time, and the speed will be very fast.

It is possible to divert the route, but it must be planned in advance, otherwise it will be troublesome to do useless work.

Where do you want to change it? If it is not appropriate, the house will pour back the cigarette.

When decorating a house, many people must know that it is especially important for kitchen flue construction. In the process of decoration and construction, the kitchen flue can not be done well, resulting in the backflow of kitchen fumes and affecting our daily life. Many old buildings are mostly brick and concrete structures, and the vast majority of flues are made of bricks, so the transverse area of the flue will be small and difficult to renovate.

In the process of home decoration, those problems should be paid attention to for flue transformation.

When renovating the kitchen flue in a new house, we must pay attention to solving the problem of smoke exhaust. Because the cross-section of the flue of the existing building cannot be expanded, for each owner, only a relatively large power range hood can be purchased to solve this problem. However, some owners have not greatly improved the smoke exhaust problem when replacing the high-power range hood by themselves.

The range hood makes a strange noise after working for a few minutes, and it is difficult to close if the kitchen door is opened. Therefore, the kitchen needs a normal one"Tuyere"。In some homes, the kitchen doors and windows are tight, so it's no wonder that the range hood makes a strange noise.

Installing valves, for retrofitting the kitchen flue, adding a valve at the flue inlet is a good solution. The valve is not bidirectional, when the range hood is used, the valve opens to the flue, and when other households discharge smoke into the flue, the valve will close tightly to prevent the flue gas from flowing back to the flue mouth, which is effectively solved"Cross-flavor"Issue. At present, there are many special flue valves on the market, and their specifications are relatively uniform.

Almost all gas pipes or gas meters in the kitchen are in the way, and the gas company is clearly more concerned about safety or ease of installation. Gas pipeline replacements must also be approved or operated by the gas company. If it needs to be replaced, in principle, the pipe separated from the gas meter should be as close as possible to the main pipe and then turned near the gas stove, and the height of the horizontal pipe should be 20 cm at the height of the ground counter.

Villa gas meters and outdoor user pipes can be transformed into wall or ground pipes. Finally, the closing door is installed at the end of the pipe.

Some kitchen flues need to be opened through the walls and storage cabinets above, so you should measure the size first, and then only prevent string smoke.

When renovating the kitchen flue in a new house, you need to pay attention to the fact that this pipe must be closed, otherwise it will be very dangerous.

You should pay attention to the direction of the smoke Buy a range hood and leave it on when cooking.

The flue is refluxed, it is easy to block, and it is necessary to pay attention to drainage and cleaning. It is also possible to add a valve at the inlet of the flue.

The first is the quality, which must not leak smoke, and then the location, which tries not to affect the overall feeling.

The first thing you notice is the problem of smoke strings, and you can buy a flue valve to solve the problem of smoke strings when you renovate.

This flue is easy to backflow, you need to pay attention to drainage, otherwise this will be difficult to clean.

The flue is public, and it is best not to change it indiscriminately.

It is possible to divert the gas, but you must use qualified staff to renovate it, that is, you must go through the open pipe, and wherever there is a joint, it must leak outside, and check whether there is a gas leak on schedule.

First of all, the kitchen flue is made of fiberglass mesh as the flue wall. If the flue wall is directly brushed with cement tiles, the flue wall will be heated in the later stage, and the thermal expansion and contraction will be easy to crack, cracking, and there will be a gap between the tiles and the flue wall pasted outside, and the oil smoke will easily drift out along the gap, and the oil smoke will always exist in the kitchen, and it is easy to induce lung cancer if inhaled for a long time, which is no less than smoking.

In this case, it is not very convenient to check, you need to knock off the tiles to check little by little, and there is no guarantee that such a problem will not occur again, so what can be done to avoid this phenomenon? The only way is to paste steel wire mesh on the cement layer of the flue wall, so what are the benefits of pasting steel wire mesh? 1. After the steel wire mesh is pasted on the flue wall, it is then flattened with cement mortar, and the steel wire mesh plays a uniform thermal conduction role, and it is not easy to crack if the heat conduction is uniform.

2. The steel wire mesh plays a role of tensile force, if the flue pipe is heated and expanded, the tensile force of the steel wire mesh can prevent the cracking of the cement mortar layer that affects the steel wire mesh and the product gap between the ceramic tile and the mortar.

3. Even if the flue wall is cracked, the cement mortar layer wrapped with the steel wire mesh will not crack, and the smell of oil smoke will still not come out, which is equivalent to double protection. Another requirement is to extend 10-15cm to the adjacent wall, why? Because the steel wire mesh is paved on the flue pipe, if the flue pipe is expanded, the steel wire mesh will be loose, so our company requires 10-15cm to extend to the adjacent wall, and the next wall is silty cement mortar and pasted with tiles, which is equivalent to saying that the steel wire mesh is firmly fixed on both sides, no matter how it is pulled, unless there is **, the steel wire mesh will be loose.

So. We are very strict about the steel wire mesh process. There are many more questions and details like this.

Because it does not occupy the steel wire mesh and does not stretch out 10-15cm, it is more convenient for the master to do things, save a little material, and also save the process of the master laying the steel wire mesh, so many guerrillas or companies that do not understand the process will ignore this problem, more because the owner does not understand, do not do it can save costs, and make more money, in fact, there are many hidden projects, if the owner does not understand very well, it is easy to be pitted, so if you know a little more, you are also a master.

First of all, look at the flue of the **, the flue of the general kitchen does not need to be deliberately treated, and it can be pasted with tiles or placed in the ceiling.

Moreover, from the perspective of building structure design, the flue cannot be changed horizontally at will due to the division of main and auxiliary flues, otherwise it will affect the smoke exhaust and there is the possibility of backfilling.

OK.

The installation of smoke exhaust pipes on the exterior wall of the house is not an illegal construction, and there is no problem in installing the flue, and the consideration is whether the material for installing the Xiye flue is suitable for installation on the exterior wall. Before installation, it is necessary to follow the safety measures and refer to the design code for building installation and smoke exhaust. Usually in the installation of the outer wall flue, a wooden frame should be built, and there is a ring such as a middle beam support, mainly to ensure the safety of construction.
